IPC: B29D30/36
Filed: 1918-07-30
Abstract: 128,777. Hopkinson, E. July 30, 1918. Vulcanizing tyres.-Relates to the manufacture of pneumatic-tyre covers and consists in subjecting the formed cover to the action of an interiorlyapplied expansible member adapted to expand the cover and stretch the threads until substantially the final size is attained, retaining the cover in the expanded condition until set and afterwards vulcanizing under direct internal fluid pressure. A cover 10, Fig. 1, after warming on a steamheated pulley 1, is placed upon a rim 9, Fig. 3, over an inflatable core 8, and is expanded by the inward movement of rings 7 by screws 12, and the simultaneous inflation of the core 8. When expanded, the rings 7 are locked to the rim 9 by spring locking-rings 5, Fig. 5. and the rim is removed with the cover, which is then enclosed by mould shells 13. Further pressure is then applied to the core 8 to expand the cover into the mould, and the cover is allowed to cool under pressure. After cooling, the cover is removed from the mould 13 and core 8 its edges are closed by a sealing-member 16, Fig. 8, furnished with grooves 20 containing unvulcanized rubber packing, and the cover is enclosed by mould members 21, which are forced together in a press and are secured by clamps 22.

Title: Improvements relating to amusement apparatus
IPC: G07F17/32
Filed: 1964-03-24
Abstract: 1,107,552. Coin-freed amusement apparatus B. J. L. WHITE. 24 June, 1965 [24 March 1964], No. 12419/64. Heading G4D. [Also in Divisions A6 and H3] An amusement machine includes an electronic pulse generator, means for continuously sweeping the pulse repetition frequency of the generator through a cycle of frequency variation, an electronic counter unit, an indicator to provide an indication of the count reached in the counter unit, manually controlled switching means for initiating the application of pulses to the counter unit irrespective of the point in the said cycle of frequency variation reached by the said pulse generator and a timing circuit for disconnecting the counter unit from the generator at the end of a predetermined period after the operation of the said manually controlled means. In a " fruit machine " type arrangement as shown (Fig. 1), on closing of a coin-operated switch 2 a master bi-stable circuit 1 is switched on and a pulse generator 3 and a sweep circuit 4 are brought into operation. When a pushbutton 11 is operated the circuit 1 is switched off and, by way of (differing) delay circuits 12-14, gates 8-10 are enabled to pass pulses from the pulse generator 3 to the electronic counters 5-7. After a predetermined time a timing circuit 15 closes the gates 8-10. The counters 5-7 each consist of three binary stages giving eight counting states. Each counter is associated with a five-lamp display circuit 16-18 (in three cases, lamps are illuminated by either of two counter states). Logical circuitry 19 including transistors is arranged so that one or more pay-out circuit sections 21 are energized when certain preselected combinations of lamp illuminations occur. Thus if a predetermined combination of illuminated lamps requiring the paying-out of twelve coins occurs and each section 21 represents the paying-out of three coins, then the fourth from last (right) section 21 would be energized (and with it those on its right) to step the pay-out circuit four times (sections 22 are delay circuits). Fig. 2 (not shown) is a circuit diagram of an alternative arrangement wherein pulses are applied to the counters simultaneously and the timing of the end of a pulse train to a counter is determined by respective different R-C timing circuits. The pulse frequency may be modulated in the range 5 to 10 pulses per second over a period of 10 seconds. The counters may be connected to the generator for approximately 2 seconds.
